The purpose of this study was to examine the influence of a supplement containing polyunsaturated phoshphatidylcholine (PPC) on physical performance, delayed muscle soreness (DOMS), markers of membrane damage, and lipid peroxidation after repeated bouts of whole body resistance on men ages 18-35 years. Subjects were randomly assigned to receive either PPC or placebo supplements for 31 days. After 3 weeks of supplementation, subjects were to perform 3 whole body resistance exercise sessions with 3 days of recovery between sessions. In order to document the effects of supplementation on recovery, fasting blood samples for determination of creatine kinase (CK) and malondialdehyde (MDA), and muscle soreness ratings were obtained each day in the morning after the initial 3 weeks of supplementation. The data was analyzed using a two-way ANOVA. The results indicate notable trends favoring PPC supplementation, such as lower ratings of perceived muscle soreness, lower CK and MDA responses to repeated bouts, improved maintenance of upper body strength and power, and increased lean body mass. However, these findings were not statistically different when compared to the placebo group. / School of Physical Education
